While I don't know any, you can easily figure it out and try if that works.

Official rules state:

pla pan tok
9 -
8 4/5 47
7 4/5 55
6 4 55
5 3w 47
4 2e+ 55
3 2w- 47

(players, panels, tokens)

I find it odd it allows 7 and 8 players to play with either 4 or 5 panels without varying the amount of token to use. I read it "you must use it, but we have to provide rules to allow you to play even if you don't have it".

Assumed that, there are two ways to amend it.

pla pan tok
9 6 55
8 5 47
7 5 55
6 4 55

the more conservative approach is to just assume they meant the western extra panel to be used and keep the tokens as they were. Problem is you would need a sixth panel to add a ninth player, and it doesn't officially exist (nor unofficially, AFAIK). If you take this route, you'll automatically also get a 10-player version, using 6 panels and 47 tokens.

pla pan tok
9 5 47
8 5 55
7 4 47
6 4 55

the optimistic approach assumes they messed up the token amounts trying to allow 7 and 8-player games to work both with 4 and 5 panels, so you fix it as in this table.

They would both need testing; before actually testing them in the field, actually counting territories and population in each panel could help (I didn't, yet).
